      @johnpoz my cable modem is an Xfinity approved Netgear CM1000.

      And I truly believe that Xfinity would love for me to replace all of my own equipment for theirs.;)

        @hpspar05 When you direct connect to the modem, what IP address do you get? The WAN address or a private address?
        What is the LAN network you are using?
        And what is the modem/gateway make/model?
        If you have VOIP phone service and wireless without additional access points, it's a gateway not a modem. FWIW, I get 300 down through pfSense and a Netgear CM600 modem on Xfinity.

        EDIT - OK, so a CM1000. Are your interfaces on pfSense all set to auto-negotiate?

          @provels I get WAN address when directly connected to the cable modem. I get the rated speed I pay for when directly connected to the cable modem, even on the test modem that was brought out yesterday, I got my rates 150mbps when directly connected to their cable modem.

          Here’s my equipment; Netgear CM1000; pfsense 2.4.4 on Protectli Vault 6 port; and UniFi Switch 8 150.

            Ah, there may be some confusion here. The technician who came out just replaced your modem? They didn't test a different router behind your modem? Or any other modem/router combo for that matter?

                @stephenw10 nope, he only test his modem and then we directly connected my laptop to it which speed was fine as usual. But once we added the wall behind the his modem, my speed reduced by half for all firewalls tested behind his and my own. So he didn’t think and I didn’t think to connect another modem behind one another, is that what you’re referring too?

                  @hpspar05 Sounds like it could be a Protectli problem to me. Maybe try one of the other opensource FW products, like OpenSense, Smoothwall, etc. to see if you get similar results.

                    @stephenw10 And yes we tested different firewalls behind both xfinity and my own modems. And he take his modem with him when he left. I don’t do Xfinity equipment if I don’t have to have it;)

                      So the Xfinity technician tested the firewall he brought with him and the speed was half?

                      If so there is nothing to talk about here. They need to fix it. There is nothing we can do for you.

                        @provels if you look back at my submissions here, I have other firewalls that were tested; SG1100, UniFi USG etc, all with the same issue behind the Xfinity cable modem and my Netgear CM1000.

                          @hpspar05 Then we'll all agree it's a Comcast issue.

                            Ok then, yeah, it has to be some upstream issue. And unfortunately it sounds like the sort of issue that Comcast will deny for as long as they can before some high level technician fixes it in 2mins. 🙄

                              @Derelict The tech only brought out a test cable modem, he didn’t have a separate Xfinity firewall if that’s a thing.

                                Whatever it is it's not pfSense. You'll have to work with Xfinity to figure out what it is.

                                  The Netgear CM1000 is generally a stellar modem. Broadcom based. Nothing wrong with those.

                                  Try spoofing the mac address of your laptop on your router WAN page. I have seen various cable ISP's hand out very different IP ranges based on MAC address.

                                        @Derelict Yes I think this is so, what’s happening here isn’t something they will own up to or fix though I believe. Ultimately, Xfinity wants people to rent their equipment.

                                          You should certainly try spoofing the MAC address to match your laptop if you have not already.
